Working with the notebook
Charging, caring for and maintaining the battery
The notebook battery can only be charged, when the ambient temperature is between 5°C and max. 35°C.
You can charge the battery by connecting the notebook to the mains adapter (see "Mains adapter connecting", Page 18).
You can increase the life of your battery by allowing it to fully discharge before recharging it again. To do this, leave your notebook turned on while operated by the battery. Once the battery is running low, you will hear a warning alarm. If you do not connect the mains adapter within five minutes of the warning alarm described above sounding, your notebook will automatically switch off.
monitoring the battery charging level
Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. When you place the mouse pointer on the battery symbol, the system displays the battery status.
The battery capacity can be monitored using an indicator which shows the current state of charge. Use the following menu to enable this feature:
Operating system | Menu |
Windows XP | Start – (Settings) – Control |
Windows Vista | Start - (Settings) - Control panel - Hardware and |
| Sound - Power options |
Windows 7 | Start – (Settings) – Control panel – Mobile PC – |
| Power options |
The indicator is then displayed in the task bar as a battery symbol. When you place the mouse pointer on the battery symbol, the system displays the battery state of charge. Please refer to the Help facility of the operating system for more information.
Battery storage
Keep the battery pack between 0°C and +30°C. The lower the temperature at which the batteries are stored, the lower the rate of
If you will be storing batteries for a longer period (longer than two months), the battery charge level should be approx. 30 %. To prevent exhaustive discharge which would permanently damage the battery, check the level of charge of the battery at regular intervals.
To be able to make use of the optimal charging capacity of the batteries, the battery should be completely discharged and then fully recharged.
If you do not use the batteries for long periods, remove them from the notebook. Never store the batteries in the device.
